Always generate timeline-data for a timeline even if the table has no
check-ins and thus no graph. This causes the timeline-data scanner to
continue looking for subsequent timelines.

Timeline styling changes: (1) The td.timelineModernCell and
td.timelineColumnarCell elements omit the id attribute when they are the
current check-out or the selection. (2) Default CSS is changed to give
a light-gray color to modern and columnar cells that are not current or
selected and do not have a branch color. (3) The detail string in the
verbose and compact views is now surrounded by parentheses.

Remove the seldom-used "Tags And Properties" section from the check-in
information screen. Move that information off into a new page /ci_tags
that includes a timeline showing all relevant timeline items in addition
to the basic tag information.
